GrunwergHCF-300M Vacuum Insulated Drinkpod Capsule Flask, Stainless Steel, Mirror, 300ml

I tried this with a cup of coffee from my bean to cup machine, so not boiling. I took sips at 2 hrs, seemed the same temperature as when it came out of the machine, at 4 hours, still very hot, and finally at 10 hours when I poured the remaining coffee into a cup and took the temperature. At over 50°c it is still warm enough to drink.It is the perfect size to take one mug of coffee. Don't fill it to the very top and it won't leak.

This is a good size to hold and to slip into a backpack, the downside being that the capacity is a bit low. It keeps an iced coffee cold for hours in a baking hot car, which is what I bought it for. It's also very easy to clean by slipping out the plastic neck insert as a bottle brush then fits easily inside the wide neck.

Great for milk storage for cup of tea.Tea in big flask, milk in this one , Delicious

Bought this for when I'm hitting the trails and need a brew while trekking.Perfect size, and keeps drinks perfect temp.Even after 4+ hours.

Great item, I’m out on the road all day and this keeps my coffee hot for hours ( probably 7)

Was smaller then I expected. But when I used the bottle, I noticed this it would not stand properly. It was tilting as very unstable. The water was also getting cold quicker, even though water is meant to stay hot. When I turned the bottle over, I noticed the damage at the bottom of the bottle. This could be a reason why my water is getting cold quicker and annoyingly tilting and unstable. Not happy with the purchase at all.

We used them to take to an outside event Brilliant and contains just the right amount

Bought for present, but was just the right size and loved the feel of the flask.
